AFAICT the circuit design and tuning controls are sophisticated,
albeit straigtforward, electronics but the big bucks are for fitting
all that into a widget the size of a fava bean.

I'd be happy to wear headphones or earbuds and carry a widget the size
of a large cell phone if it worked for my hearing loss and cost a few
hundred bucks instead of the ca. $2,000 per ear.

Bandwidth tuning, noise cancellation -- what else?  See
"sophisticated" supra.  I'm guessing that "adjusting" a modern hearing
aid is done by connecting it to a computer and proprietary software.
They're too small to support an array of little adjusting screws.

Where's this happening?  I high-frequency loss, speech discrimination
loss and tinitis.  But I'm weak on serious math and know almost noting
about electronic hardware.  There was a brief flurry of interest in
DSP projects in Halifax (NS) circa 1994 but I think it's faded away.

Wroking around loud engines, running power tools and hammering at the
anvil are quite enough, thanks, without rock n' roll.
